Liquid insecticide dispenser



Oct. 6, 1964 J. v. SCARPA 3,151,785

LIQUID INSECTICIDE DISPENSER Filed June 12, 1962 JAMES V.50A/PPA United States Patent 3,151,785 LIQUID INSECTICIDE DISPENSER Iames V. Scarpa, Oak and Maine Road, Vineland, NJ. Filed June 12, 1962, Ser. No. 201,935 1 Claim. (Cl. 222-478) This invention relates to a novel dispenser for a liquid insecticide and more particularly to a container having means for controlling and regulating the rate that the liquid contents thereof is dispensed from the container.

Another object of the invention is to provide a container of unique shape which will enable it to be readily positioned in relatively inaccessible locations.

Still a further object of the invention is to provide a container having means whereby the container can be disposed at an incline downwardly and toward its discharge end when resting upon a substantially horizontal surface, whereby all of the contents of the container can be dispensed therefrom.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof, and wherein:

FIGURE 1 is a top plan View of the dispenser;

FIGURE 2 is a longitudinal sectional view thereof, taken substantially along the line 22 of FIGURE 1, and showing the dispenser in an applied position;

FIGURE 3 is a cross sectional view taken substantially along the line 33 of FIGURE 1;

FIGURE 4 is a cross sectional View taken substantially along the line 44 of FIGURE 2;

FIGURE 5 is an enlarged fragmentary sectional view of a part of the container, and

FIGURE 6 is an enlarged side elevational view of another part thereof.

Referring more specifically to the drawing, the liquid insecticide dispenser in its entirety is designated generally 8 and includes an elongated container or bottle 9 having a substantially flat bottom 10 which extends from endtoend thereof, and a top 11. The marginal edges 12 of the bottom 10 and top 11 merge integrally with one another, as clearly shown in FIGURES 2 and 4. One end of the container 9, constituting its forward end 13, terminates in a forwardly extending forwardly opening neck 14, formed by a portion of the bottom 10 and top 11. The container 9 is flared laterally from adjacent the neck 14, as clearly seen in FIGURE 1, so that the neck is of relatively small diameter as compared to the width of the container at its opposite rear end 15 and throughout a major portion of its length. The container 9 has a straight longitudinal side edge 16 extending from its rear end 15 to its forward end 13 and along which the neck 14 is disposed, as clearly illustrated in FIGURES l and 3.

The container 9 includes a rib 17 which is formed integral with and projects downwardly from the bottom 10 and which extends across the rear end 15. The neck 14 is provided with a surrounding outwardly opening groove 18. As best seen in FIGURES 2 and 3, the top wall 11 is bulged upwardly relative to the bottom 10 from adjacent the neck 14 so that it includes a gradually sloping upwardly and rearwardly extending front portion 19 and a convexly rounded more sharply sloping downwardly extending rear portion 20. The top wall 11 is convexly rounded in transverse section, as clearly illustrated in FIGURES 3 and 4.

The dispenser 8 additionally includes a cap 21 which fits snugly over the neck 14 and which is secured nondetachably thereto by an adhesive 22 contained in the groove 18. The cap 21 has a flat outer end wall 23. One end of an elongated rigid vent tube 24 extends outwardly through a part of the end wall 23 so that said end of the tube opens externally of the cap 21 to the atmosphere. The tube 24 is inclined upwardly from adjacent the inner end of the cap 21 to extend upwardly toward the topmost central portion of the top wall 11 in order that the other end 25 thereof will be disposed in an air chamber 26 of the container 9, disposed above the level of the liquid insecticide 27 of the container, when the container is disposed in a normal position for use as illustrated in FIGURE 2. The cap 21 also includes a rigid dispensing tube 28 having a right angularly turned inlet end 29 which extends inwardly through the cap Wall 23, below the vent tube 24, so as to open into the neck 14. The other longer end 30 of the tube 28 is substantially straight, and is disposed externally of and substantially parallel to the plane of the end wall 23 and extends downwardly from the cap 21. Said end 30 terminates in a beveled discharge end 31.

The dispenser 8 is intended to be substantially filled with the insecticide 27 after which the dispensing cap 21 is applied and secured thereto. A closure member 32, as seen in FIGURE 6, engages over the portion 30 of the discharge tube 28 for closing and sealing its outlet end 31 until the dispenser 8 is ready for use.

FIGURE 2 shows the dispenser being utilized to impregnate a sill 33 of a building foundation. A nail or other sharp instrument, not shown, is utilized to form an upwardly opening bore or depression 34 in the sill 33 in which the discharge end 31 of the tube 28 is received, preferably with a relatively snug fit and with clearance between the tube end 31 and the bottom of the depression. It will be understood that the closure 32 is removed before the tube end 31 is inserted in the depression 34. A part of the dispensing cap 21 and the rib 17 will rest upon the substantially horizontal top surface of the sill 33, so that the flat bottom 10 will be disposed slightly elevated and at an incline downwardly and toward the neck 14. When the container 9 is thus disposed, the vent tube end 25 is located in the air chamber 26 for venting said chamber to the atmosphere. The bore of the tube 24 is very small so that air enters the container 9 at a very slow rate, and the bore of the tube 28 is likewise very small so that the liquid insecticide 27 can merely seep therefrom to impregnate the sill 33. Thus, depending upon the size of the container 9 and the bores of the tubes 24 and 28, the dispenser 8 can function for a period of from three to six months to maintain a member impregnated with the insecticide 27 and before all of the contents of the container 9 has been dispensed.

Due to the shape of the container 9, it can readily be positioned in relatively inaccessible spaces and requires no special skill or tool to apply and utilize said dispenser. Additionally, the dispensing tube 28 can be located in close proximity to a corner of a foundation or along an upright wall due to the fact that the dispensing cap 21 and neck 14 are located along the longitudinal side edge 16.

It will be understood that the dispenser 8 can be utilized for dispensing an insecticide into various building materials including wood and cement and is thus especially adapted for dispensing an insecticide for destroying terminates.

The dispenser 8 may be formed of various materials including metals and plastics. The tubes 24 and 28 are preferably formed of either brass or copper.

Various modifications and changes are contemplated and may be resorted to, without depanting from the function or scope of the invention as hereinafter defined by the appended claim.

I claim as my invention:

A liquid insecticide dispenser comprising an elongated rigid container of substantial width having a substantially fiat bottom extending from end-to-end of the container and an upwardly bowed top wall raising from the side edges of the bottom and including an upwardly bulged topmost portion, said container having a restricted outwardly opening neck at one end thereof, a bottom part of said neck being disposed flush with said bottom and another part of the neck being disposed flush with a straight side edge of the container, a cap disposed over and sealed to said neck, a vent tube supported by said cap having one end opening therethrough to the atmosphere and an opposite end opening into said topmost pontion of the container, and a dispensing tube supported .by said cap having a discharge end disposed externally of the cap and extending laterally therefrom, said dispensing tube having an inlet end angularly disposed relative to said discharge end and opening through a cross of said cap into the neck, said 4 vent tube and dispensing tube each being of small part sectional size and each having a minute bore extending therethrough for substantially restricting the rate of gravity discharge a liquid insecticide from the container through the dispensing tube.
